BOTTLE CAP AND THE LIKE.

Application filed February l9, 1920. Serial No. 359,790.

To all whom it may concem Be it known that I, FREDERIC K. PLYMP- TON, acitizen of the v at \Vellesley, in the county of Norfolk, State .5 ofMassachusetts, have invented a certain new and useful Improvement inBottle Caps and the like, of which the following is a specification,reference being had therein to the accompanying drawings.

The object of the invention is to provide an improved closure for a milkbottle or the like of a type adapted to completely enclose I and coverthe mouth of the bottle or jar. In practice milk bottles andjars arecommonly sealed by a flat disk which is seated in the mouth of the same.This method of sealing has the objection that opportunity is presentedfor the collection of waste milk, water, pieces of ice and .dirt in theopen space above the disk, so the contents of the bottle or jar areliable to be contaminated I removed, by the falling of the samei'nto thebottle.

plated by this invention may go lnto general use it is necessary, notonly that it completely enclose and cover the neck of the bottle, butthat it may be easily applied to the bottle, as well as readilyremoved'from the same without the use of special tools, and that when soremoved, .no part of the cap or its retaining means shall be left uponthe bottle, causing additional labor at the bottling plants; and thatthe cap with its 5 retaining means can be manufactured and sold at a comaratively lowcost. It is also desired that the cap and its retainingmeans be supplied to the trade in assembled form ready for applicationto the bottle as a single 40 unit.

A cap of metal is too expensive for common use, and consequently the capmust be made of a non metallic material, preferablyof paper or pulpboard, which can be easily! formed into the desired shape. It isnecessary to provide the cap with some form of fastening means in orderthat the cap may not be accidentally dislodged from the bottle to whichit has been applied. The invention resides more particularly in novelretaining or fastening means and the combination of the same with a cap.

Referring to the drawings,

F lg, 7 is a s1de elevation of a cap and its retaining means in crimpedform ready for appl cation to a bottle.

in horizontal section on i the neck of a bottle and made fast thereon offlexible material,

preferab a er "or pulp board, with the 1y p p dependent flange 2,

said flange being of larger diameter at'the' bottom than at theftop.Near the. bottom of the flange is applied the retaining means strip ofwire preferably, the ends of, which are overlapped with the body 1, asat 3, which consists of a each other when ap lied to 4, Figs and 7, atho it may be a continuou's mug. This wire is formed with integral'PI'OJGCtlOIlS 5, 5, at intervals, as in F 1g. 5, Which preferably isaccomplished by bendlngthe wire to form U-shaped lateral pro ect1on sand closing the sides of the open portions of each' U togeth that theyare parallel .or

In the process of making the cap the body 1 is mou ded to give it theshape shown in Figs. 1 and 7 and to tened crimps the fulness'of theskirt or flange thereof, and then the retaining means 61', as in Fi 5PProximat L press down into flat-v 3 is applied; to the skirt or flangeby forcing i jections into hook-form and clinching them at the innersurface of'the skirt or, material, as in Fig.2. In making application-ofthe retainer 3 to the skirt or flange and fastening the same thereto,the two ends of the retainer are overlapped at 4 and respectively arefastened to the skirt or flange at or beyond the point of meeting, sothat the skirt or flange is held securely within the ring formed by theretainer in its ap lied A short portion 0 one extremity, beyond thepoint at which the .25 ing the skirt or flange and its applied re tameraround the neck.

latter is fastened to the skirt or flange, isv

left free to be raised and taken hold of in unfastening the cap, throughdisengagement of the fastening projections of such extremity from theskirt or flange, to provide for its removal.

applicationof the finished cap to a bottle the final crimping by whichthe cap is secured in place may be more easily effected, andregi-ilarity and uniformity of the crimps as in Fig. 'tmay beestablished.

The cap is applied to a bottle and fastened in place thereon b placingit over the mouth and neck of the ottle and compress- The cap will be I1' securely held in place by means of the comat 6, Fig. "it can begrasped by slippage in the operation of removing the cap from the bottleto which it has pressed retainer.

In some cases, the unattached finger-hold ortion of one end of the stripconstituting a retainer may be folded back upon itself as 5, orotherwise be so formed that ones fingers without been ap lied.

' 0 remove the cap, the finger-hold portion is grasped and by pullingoutwardly thereon the strip of wire is easily pulled from the skirt orflange, which will allow the cap to be lifted from the bottle. The

' strip can be entirely detachedin this operaso forming the tion, oronly loosened sufficiently to the cap to be removed.

It is impossible to remove a cap of the general type including my own,and replace the permit same -after' the'contents of the bottle have beentampered with, without detection. The invention aims to meet thisrequirementby retaining means and fastening the cap to the bottle thatthe removal of .handle in disengaging the the cap shall so damage itthat it cannotbe again rescaled upon the bottle, although it maiy beused for a temporary cover.

t will be seen that the complete cap can be simply and inexpensivelymanufactured as a complete unit in automatic machinery.

I claim: i

1. Ab'ottle orjar cap comprising a flanged body of flexible materialhaving combined with its depending flangea non-continuous fastening ringhaving overlapping end-portions fastened to the said fian-geat or be;yond the point of meeting, one of such endportions being adapted to beused as a fastenings' of such end-portion for loosening the cap from thebottle or jar to 'which it has been applied.

2, A bottle or jar cap comprising a flanged body of flexible materialhaving combined with its depending flange a non-continuous ring havingintegral fastening hooks constituted by U-shaped projections formed atintermediate points in the ring, with the open portion of the U closedtogether and the sides thereof approximately parallel to each other. j

3. A bottle or jar cap comprising a flanged cap of flexiblematerialhaving combined with its depending flange a non-continuous ringwith overlapping ends, fastened to the flange by integral U-shapedprojections formed at intermediate points in the strip of material ofwhich the ring is made, with the side portions of th U closed together,and

with said projections extending through the.

material of the flange and clinched.

4. A bottle or jar cap comprising a flanged cap of flexible non-metallicmaterial having combined with its depending flange a metal ring fastenedthereto=-by means of integral retainlng hooks constituted by U-sh'apedprojections formed at, intermediate points of said .ring and havingtheir sides closed together and approximately parallel, with the desiredby! the trade that it shall be of the flange and the ends thereofclinched.

projections extending through the material In testimon whereof I aflixmy signature in presence 0 two witnesses.
